Robert Metzger created FLINK-1572:
-------------------------------------
Summary: Output directories are created before input paths are
checked
Key: FLINK-1572
URL: https://issues.apache.org/jira/browse/FLINK-1572
Project: Flink
Issue Type: Improvement
Components: JobManager
Affects Versions: 0.9
Reporter: Robert Metzger
Priority: Minor
Flink is first creating the output directories for a job before creating the
input splits.
If a job's input directories are wrong, the system will have created output
directories for a failed job.
It would be much better if the system is creating the output directories "on
demand" before data is actually written.
